Problems solved by technology

[0004] Traditional design usually only seeks single-objective optimization in the scheme design period, and cannot guarantee the optimal design of multi-objective overall effect; the prototype is manufactured according to the design scheme, and then the feedback design is corrected after the bench test, which is time-consuming, consumable, and labor-intensive, resulting in a long cycle , and the experiment inevitably has the chance of individual cases

Abstract

The invention discloses a multi-target optimization robust collaborative design method for a transmission chain of a low-wind-speed wind turbine generator, and belongs to the field of wind power generation. According to the technical scheme, the method is characterized by comprising the steps: 1, formulating evaluation standards of a low-wind-speed wind turbine generator transmission chain system;(2) formulating selection indexes and evaluation factors related to a transmission chain and components; 3, setting the weight of each design evaluation factor; 4, employing experts and setting influence weights; 5, scoring each scheme by each expert; 6, calculating a weighted average value of each scheme; 7, performing comparing to obtain a transmission chain design scheme with the highest score; and 8, obtaining an optimal low-wind-speed wind turbine generator transmission chain design scheme. According to the method, the problems that a low-wind-speed wind turbine generator has higher requirements on the transmission chain and the optimal design scheme of the transmission chain is not easy to determine are solved.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a method for multi-objective optimization and robust collaborative design of a transmission chain of a low wind speed wind turbine. Background technique [0002] With the leap-forward and rapid development of wind power in the past ten years, the development of wind power in areas rich in wind energy resources and relatively rich areas has become saturated, and because the construction of supporting power grids cannot keep up, some areas rich in wind energy resources cannot be built temporarily; The development of low wind speed resources with 68% of the area of ​​wind energy resources has become the main direction of wind power development in my country; while low wind speed resources in my country are mainly distributed in the central, eastern and southern regions, which not only have high corrosion, high temperature corrosion, high temperature corrosion, high temperature and...
